Answer» Answer: 3n2 - 3N - 1 Step-by-step explanation: Equation at the end of step 1 (3n2 - 3n) - 1 STEP 2 : TRYING to factor by splitting the MIDDLE term 2.1 FACTORING 3n2-3n-1 The first term is, 3n2 its coefficient is 3 . The middle term is, -3n its coefficient is -3 . The last term, "the constant", is -1 Step-1 : Multiply the coefficient of the first term by the constant 3 • -1 = -3 Step-2 : Find two factors of -3 whose sum equals the coefficient of the middle term, which is -3 . -3 + 1 = -2 -1 + 3 = 2 Observation : No two such factors can be found !! CONCLUSION : Trinomial can not be factored Final result : 3n2 - 3n - 1 plz mark me brainliest |
